Upgrading bitnami/moodle container

I have a setup based on what is described in https://hub.docker.com/r/bitnami/moodle ``` # Copyright Broadcom, Inc. All Rights Reserved. # SPDX-License-Identifier: APACHE-2.0 version: '2' services: mariadb: image: docker.io/bitnami/mariadb:11.3 environment: # ALLOW_EMPTY_PASSWORD is recommended only for development. - ALLOW_EMPTY_PASSWORD=yes - MARIADB_USER=bn_moodle - MARIADB_DATABASE=bitnami_moodle - MARIADB_CHARACTER_SET=utf8mb4 - MARIADB_COLLATE=utf8mb4_unicode_ci volumes: - ./mariadb_data:/bitnami/mariadb moodle: image: docker.io/bitnami/moodle:4.3 ports: - '80:8080' - '443:8443' environment: - MOODLE_DATABASE_HOST=mariadb - MOODLE_DATABASE_PORT_NUMBER=3306 - MOODLE_DATABASE_USER=bn_moodle - MOODLE_DATABASE_NAME=bitnami_moodle # ALLOW_EMPTY_PASSWORD is recommended only for development. - ALLOW_EMPTY_PASSWORD=yes volumes: - ./moodle_data:/bitnami/moodle - ./moodledata_data:/bitnami/moodledata depends_on: - mariadb ``` The moodle version in site administration - notifications: Moodle 4.3.2 (Build: 20231222) I want to upgrade the moodle instance to moodle:4.4 and for some reason thought it'd be as simple as updating the docker-compose.yml and restarting the stack. But, it does seem that there is much to do and I don't quite understand how to do this. I also noticed that I would like to have all the language versions available so I created Dockerfile with only `FROM bitnami/moodle` and docker-compose.yml ``` # Copyright Broadcom, Inc. All Rights Reserved. # SPDX-License-Identifier: APACHE-2.0 version: '2' services: mariadb: image: docker.io/bitnami/mariadb:11.3 environment: # ALLOW_EMPTY_PASSWORD is recommended only for development. - ALLOW_EMPTY_PASSWORD=yes - MARIADB_USER=bn_moodle - MARIADB_DATABASE=bitnami_moodle - MARIADB_CHARACTER_SET=utf8mb4 - MARIADB_COLLATE=utf8mb4_unicode_ci volumes: - ./mariadb_data:/bitnami/mariadb moodle: #image: docker.io/bitnami/moodle:4.4 build: context: . dockerfile: Dockerfile args: - WITH_ALL_LOCALES=yes ports: - '80:8080' - '443:8443' environment: - MOODLE_DATABASE_HOST=mariadb - MOODLE_DATABASE_PORT_NUMBER=3306 - MOODLE_DATABASE_USER=bn_moodle - MOODLE_DATABASE_NAME=bitnami_moodle # ALLOW_EMPTY_PASSWORD is recommended only for development. - ALLOW_EMPTY_PASSWORD=yes volumes: - ./moodle_data:/bitnami/moodle - ./moodledata_data:/bitnami/moodledata depends_on: - mariadb ``` Could someone provide a step-by-step instructions how I get from old setup to new setup without losing my data?
